3.Mount the Transformer Option #2
3.2 Option 2:Brick or Cement Wall Mounting
Drill two holes of 5/16(8mm),4-9/16”(11.6cm) apart from each other, in a wall near an electrical outlet and place
the two plastic anchors included. Insert the two support screws in the anchors until they have about 1/4”(6mm)
of space left to mount the transformer.
Landscape wire to the fixtures.
4.Mounting the Photocell
Mount the photocell (B) bracket on a wall or other solid surface with the screws (B2，
B3，B4) provided. Snap the sensor into the bracket. Route or coil the excess wire to
protect it from lawn mowers, trimmers, etc. Avoid pointing the sensor at nighttime light
sources such as windows, porch lights, and street lights.
Connect the photocell to the transformer, insert the wire plug from the photocell to the
transformer socket and rotate anticlockwise until it secures.
Placing the sensor in areas receiving less sunlight at dusk (east side of house, behind
trees and bushes, under a deck) will have the transformer come on earlier in the evening.
Mounting the photocell in brighter locations will have the transformer come on when it
has become darker out. The location, position and orientation of the photocell can be
adjusted until the transformer turns on at the desired light level. If the wires to the
photocell are cut or broken, the photocell can be replaced. Unscrew the photocell
connector cover from the transformer and pull the bi-pin connector out of the mating
socket. The replacement part is inserted into the socket and the cap is screwed back onto
the socket to provide a water tight connection. Note that the bi-pin connector is polarized
and can be inserted into the socket only one way. The photo eye operation can be tested
by turning the transformer mode to TEST. Replacement photocell is available in the
store.

5.Run the landscape Wire (Not Included)
The landscape wire should run from the transformer to each light without being cut. Do not
run the landscape wire within 10 feet(3M) of a pool, spa or fountain. If the landscape wire is
too long, cut it with a cable cutter.
